Section 4. PC9000 SDK
4.1 PC9000 SDK Overview
The PC9000 SDK allows software developers to create custom datalogger
application programs using such programming languages as Visual Basic or
Delphi. The PC9000 SDK includes the latest PC9000 DLL that provides a full
and varied set of datalogger control and data collection functions.
The PC9000 SDK is tailored toward direct, high-speed, real-time
communications between the PC and a single datalogger. The SDK currently
supports communications with CR9000, CR9000X, and CR5000 dataloggers
only.
4.1.1 PC9000 SDK Configurations
The included PC9000.DLL is a standard call-level DLL meaning that at this
time it does not support OLE automation and does not need to be registered in
the system registry. The SDK also includes associated drivers and currently
supports the following CSI datalogger configurations:
• CR9000 connection via a BLC100 PC Bus Link Card (TLink) for
Windows 95/98/ME only
• CR9000 connection via a PLA100 Parallel Port Link Adapter (LPT)
• CR9000 connection via a TL925 RS-232 Interface (COM)
• CR9000 connection via a NL105 Network Link Interface (NET)
• CR9000X or CR5000 connection via a 9-pin RS-232 serial cable (COM)
• CR5000 connection via a NL100/NL105 Network Link Interface (NET)
4.2 PC9000 DLL Usage
By default, the PC9000.DLL will be installed in the
C:\Campbellsci\PC9000SDK\DLL\ directory. Before distributing a created
software package, you must do one of the following to ensure the DLL can be
found by your application:
• Place the DLL in the application directory.
• Create a new PATH environmental variable describing the location of the
PC9000.DLL during install.
• Place the DLL in the "Windows System" directory during install. The
Windows System directory is normally C:\WINDOWS\SYSTEM for
Windows 95/98/Me systems, C:\WINNT\SYSTEM32 for Windows NT
4.0 and Windows 2000 systems, or C:\WINDOWS\SYSTEM32 for
Windows XP systems.
